Adhesive dispenser system

Abstract

A dispenser system employs a packaging module for use with moisture sensitive materials. The packaging module comprises an outer carton and an inner bladder, which is substantially impermeable to moisture and is filled with one part of an adhesive. The carton is loaded on a mobile cart and the one part adhesive is supplied to a pump / mixer without exposure to moisture in the atmosphere. The packaging and dispensing system can be used in conjunction with mechanized adhesive application equipment for the construction trades. A cart which employs multiple transversely spaced mixing nozzles is employed to produce transversely spaced beads of adhesive as the cart is pushed along a surface. Part 1 adhesive component and part 2 adhesive component are independently pumped to mixing nozzles which dispense the adhesive in beads.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 11 / 818,451 filed on Jun. 14, 2007 now U.S. Pat. No. 8,167,170, which claims priority of U.S. Provisional Application No. 60 / 813,788 filed on Jun. 15, 2006.FIELD OF THE TECHNOLOGY[0002]This application is directed to a packaging system for moisture-sensitive materials, and more particularly, to a dispensing system for moisture-sensitive adhesive materials used in the construction industry.BACKGROUND OF THE INVENTION[0003]In the construction industry, most moisture-sensitive materials, such as adhesive components, are packaged in a variety of sealable containers to prevent the contents from absorbing water from the atmosphere or moisture that collects on the surfaces of dispensing systems. Moisture commonly migrates into the fittings, nozzles and conduits of such dispensing systems. The dispensing system becomes clogged and the dispensing qualities are degraded to...

AI Technical Summary

Benefits of technology

The patent is about a system for dispensing adhesive. It uses a special packaging module that protects the adhesive from moisture, and it can be used with mechanical or motorized applicator systems. The packaging module is designed to be efficient in using adhesive, and it has a retention flange that keeps it stable on a tray. The system also includes a connector assembly that connects to a conduit and does not allow moisture to expose the adhesive. Overall, this system makes it easier and more convenient to use adhesive for construction purposes.

Problems solved by technology

The dispensing system becomes clogged and the dispensing qualities are degraded to the extent that the system must be disassembled and cleaned.

Significant costs and inefficiencies result from having to remove moisture which collects in the components of the dispensing system.

However, moisture-sensitive materials are inherently difficult to store after opening the original packaging, so in many cases, the unused portion is discarded after a construction job is completed.

If moisture-sensitive materials are not discarded after opening the primary container, the material begins to chemically degrade, which can negatively affect the performance and physical properties of the remaining material.

Additionally, the necessity of routinely discarding the unused portions of moisture-sensitive materials is costly, inconvenient, and environmentally unsound.

At least one of the connector assemblies upon connection to the conduit does not permit exposure of the component in the bladder to the atmosphere.
